Abstract

The intraoral scanner in the market contends with challenges, specifically in accurately detecting metallic surfaces of prostheses affected on the fitness of the restoration; therefore, several scanning agents were used to evaluate the internal fit of the zirconia crown.

45 prefabricated titanium abutments (n = 45) were selected for this study. Samples were divided into three groups (n = 15 each) according to the application of scanning aid agents. Group 1 (G1: control) used a scan body; G2: used liquid paint as the scanning aid agent; and G3: used powder spray as the scanning aid agent. Each abutment was applied with an imaging scanning aid agent to scan and mill the crown. All scans were performed using the same intraoral scanner, and the internal fit was analyzed digitally using digital silicone replica techniques and Geomagic Control X software. Statistical analysis was performed using the one-way ANOVA test.

There was no significant difference among the three groups.

Scanning aid agents showed similar accuracies for the internal fit of the crown, with no significant differences observed.
